I'm sure to any of you that stumble across this looking for audio effects and not into much else electronically, is going to seem like greek but the arduino programmer is a brilliant little device, and comes in handy with alot of projects, one example being that I made an EMF detector to see how heavy the magnetic radiation I am exposed to was, but not only that you can do things like add LCDs to your existing projects, make automated controls for your pedals and so on, and even make a few really cool DSP guitar effects as youll find on instructables.com
first off, heres a link to introduce you to Arduino arduino.cc/en/Guide/Introduction

with this project you'll still need to buy the programmer (I've got the Duemilanove version) but my stripboard enables you to make many projects with the microprocessors the Duemilanove programs, without having to buy a new Duemilanove or whichever you have/getfor each thing you make, anyway DON'T be afraid to go into this, it is alot easier than it looks to work.

this is compatible with both the ATmega168 and the ATmega328 chips ( I accidently put ATmega128 on the layout below it is meant to be ..168)

LED 1 is the power LED
LED 2 is the blink LED - when you use the chip from arduino it will be preloaded with a flash sequence so you know its working - that LED will be the one that flashes.

the switch resets the "sketch" (program)



Examples of it in use...
EMF Detector (you can use it if youre one of those people who think ghosts carry around giant battery packs to give off EMF too.)



and I messed about with a few jumpers to make an LCD tag for my band

this is the ChuMoy Acoustic simulator, this basically centers alot of the frequencies from stereo channels which is very
handy when listening to harshly panned music on headphones (beatles to name one such offender)

and a giant greek cat Fergie


if you want to build this monstrosity the perf layout can be found here :

I needed something to switch on a relay with a push to make switch and then turn off when you push the button again so heres one idea...
this is useful for effects pedals because it can be made out of salvaged parts rather than spending tons on a latching stompswitch



from this schematic

this is a valve emulator, the pot is facing upwards

I've not built this yet so i'll put up the schematic also in case I got something wrong
im pretty sure I got it right, and even if I have im not sure if the schematic works in
the first place so... when I make it i'll edit this to say if it worked or not, if anyone else
builds this let me know if it works.
